Abstract
A patient support device for a radiation therapy system has a load-bearing element, which is set up so as to be supported rotatably on a stationary structure about a vertical iso-axis extending through a treatment iso-center. The load-bearing element, with a patient tabletop mounted on it, can be leveled by a continuously adjustable leveling device. The leveling device is embodied in particular as a leveling shoe, which includes a bottom plate, a top plate, and an adjustable wedge disposed between them.
Claims18
A patient support device for a radiation therapy system comprising:
- a load-bearing element supported rotatably on a stationary floor of a well structure about a vertical iso-axis extending through a treatment iso-center;
- and
- a patient tabletop mounted on the load-bearing element,
- wherein at least one continuously variable leveling device serves to orient the load-bearing element,
- wherein the at least one continuously variable leveling device includes a bottom plate, a top plate, and an adjustable wedge disposed between the bottom and top plates, and
- wherein the at least one continuously variable leveling device is disposed such that a horizontal motion of the adjustable wedge causes a vertical motion of the load-bearing element.
A patient support device for a radiation therapy system comprising:
- a load-bearing element supported rotatably on a stationary floor of a well structure about a vertical iso-axis extending through a treatment iso-center;
- and
- a patient tabletop mounted on the load-bearing element,
- wherein at least one continuously variable leveling device serves to orient the load-bearing element,
- wherein the at least one continuously variable leveling device includes a bottom plate, a top plate, and an adjustable wedge disposed between the bottom and top plates, and
- wherein the at least one continuously variable leveling device has a horizontally supported threaded spindle for adjusting the wedge.
A patient support device for a radiation therapy system comprising:
- a load-bearing element supported rotatably on a stationary floor of a well structure about a vertical iso-axis extending through a treatment iso-center;
- and
- a patient tabletop mounted on the load-bearing element;
- wherein at least one continuously variable leveling device serves to orient the load-bearing element, and
- wherein the load-bearing element is mounted at least in part in the floor well functioning as the stationary structure, and the floor well on its bottom face, has a mounting face of concrete, in which levelings are anchored directly.
